| 摘 要： | We investigate the effects of target deformation on the synthesis of superheavy nucleus 283^112 in the framework of the extra-push model. Our results show that the cross sections of the 3n evaporation residue in the 48^Ca 238^U reaction for the case of β2=0.275 are several times larger than those of β2=0. Meanwhile, the peak position of ER excitation function in the case of the deformed target is shifted to lower energy as compared to that of the spherical target.
